The quality of nanoparticles that are obtained by spray flame synthesis depends strongly on the thermophysical properties of the precursor solutions. Solutions of iron(III) nitrate-nonahydrate (INN) in ethanol are interesting precursor solutions for the production of iron oxide nanoparticles in these processes. However, no data on the thermophysical properties of solutions of INN in ethanol are available in the literature. Therefore, in the present work, the specific density, viscosity, thermal conductivity, and molar isobaric heat capacity of solutions of INN in solvent mixtures of ethanol and water were measured at 101.3 kPa between 288.15 and 333.15 K, solvent compositions ranging from pure ethanol to pure water, and INN molalities up to 1.3 mol kg^–1. Empirical correlations of the experimental data are provided.

乙醇和水的混合物中的硝酸铁-水合硝酸铁溶液的热物理性质

通过喷雾火焰合成获得的纳米颗粒的质量在很大程度上取决于前体溶液的热物理性质。硝酸铁（九水合硝酸铁）（IIIN）在乙醇中的溶液是在这些方法中生产氧化铁纳米颗粒的有趣前体溶液。然而，在文献中没有关于INN在乙醇中的溶液的热物理性质的数据。因此，在本工作中，在288.15和333.15 K之间的溶剂组成范围为101.3 kPa，测量了INN在乙醇和水的溶剂混合物中的比重，粘度，热导率和摩尔等压热容，溶剂组成从纯乙醇到纯净水，INN浓度最高为1.3 mol kg ^–1。提供了实验数据的经验相关性。
